“When you do a long running show, sometimes things can get crabby," Wendy said. "But my guys in the band, they are so grateful, they are so happy to be here.”

The show based on songs by the Swewish pop group ABBA has been on the great white way for almost 13 years- and it's shown no signs of slowing down. MAMMA MIA! has already graced the stage for more than five thousand performances.

"ABBA I would say has this heart and there’s this kind of folksiness to some of their music," Wendy said. "There’s depth, but there’s a lot of sheen."
